Hello, Yes, Krimson 35 is not a medicine that can clear unwanted things from stomach. There is a chance of some misunderstanding between you and the prescribing doctor if only clearing stomach is the issue. Krimson 35 is a hormonal medicine. It is given as a contraceptive to prevent pregnancy and also as a cure for Polycystic Ovarian Disease (PCOD). PCOD is basically a disorder that causes female hormonal disturbances, resulting in irregular egg formation in the ovaries resulting ultimately in irregular periods. This condition is most of the times associated with obesity. So if your wife had any of these menstruation related problems or wanted contraceptives to prevent pregnancy or if doctor suggested that obesity is related to some hormonal disturbances, taking Krimson 35 is advisable. In any other case, she should go for blood tests to rule out thyroid disorder, diabetes or other metabolic problems to diagnose the reason behind suddenly increased weight without any apparent reason and treatment should be given accordingly. To explain how Krimson 35 works, it simply gives right messages to ovaries to produce female sex hormones at the right time in the right amounts and makes periods regular. Krimson 35 is a pretty safe medicine and does not cause much or severe side effects. Some of the adverse reactions include nausea, breast tenderness, decreased sexual desire and change in menstrual flow. If the menstrual flow increases or decreases drastically, you should contact the doctor to adjust dosage. Some women take this drug for years together without experiencing any adverse effects.
